One of the biggest reasons Stranger Things was such a huge success is because it managed to successfully capture the spirit of what it was like watching a paranormal '80s movie. There was a certain magic about those films, where everyday people and total losers were faced with crazy circumstances.

The show's a master class in "good nostalgia" for accomplishing this and fomenting a newfound obsession with everything from the '80s.

So it only makes sense that Emporium, a retro Arcade bar in Chicago, created a Stranger Things pop-up bar called "The Upside Down." It offers cocktails inspired by the show. Like "Eleven's Eggos," a drink that's garnished with a toasted piece of the weaponized child's favorite food.

The pop-up bar was a raging success. In fact it was so successful that the folks at Netflix took notice. Problem is, Emporium didn't get permission to start throwing around Stranger Things likenesses before they made the bar.

Netflix sent them a cease and desist letter, however, they loved the fact that the bar was a huge fan of the show. So they responded in fan-language and the result was this amazing piece of correspondence.

Yes, I know, it's quite possibly the coolest legal document of all time.

If you're in Chicago, you might want to give the pop-up bar a visit before it closes up shop on October 1st. Otherwise, look out for the second season of Stranger Things, hitting Netflix on October 27, just in time for Halloween.
